Canberra's Duplicate Image Problem: The Key Decisions Ahead for Government Archives

Canberra's public sector is facing a crunch point over how it handles thousands of duplicate digital images stockpiled across agency servers, with a series of decisions about storage contracts, archival policy, and software procurement expected to crystallise before the end of the 2026 calendar year. The problem is neither new nor glamorous, but the costs are becoming impossible to ignore.

The timing matters because several federal agencies are mid-cycle on their cloud storage agreements, many of which were struck in 2021 and 2022 during the accelerated digitisation push that followed pandemic-era lockdowns. Those contracts are expiring or due for renegotiation, forcing ICT managers to confront the scale of duplicate image data they have been quietly accumulating. For a city whose economy runs almost entirely on public administration, this is not a back-office annoyance — it's a budget question.

What the Duplication Problem Actually Looks Like

The issue is straightforward in principle, expensive in practice. When staff scan, upload, or migrate documents, images are frequently saved multiple times under different file names or in different folders. Across a large agency with thousands of employees, that compounds fast. The Australian National Audit Office has previously identified data governance and digital asset management as recurring weaknesses in federal department ICT audits, though specific duplication figures vary agency by agency and are rarely disclosed publicly.

At the Australian National University on Acton Peninsula, library and research data teams have grappled with comparable problems in managing digitised archival collections. The university's Scholarly Information Services division has invested in deduplication software as part of broader repository management, a model some ACT government bodies are now studying. Similarly, the Department of Finance, headquartered on King Edward Terrace in Parkes, has flagged digital asset rationalisation as part of its whole-of-government ICT strategy work, though details of specific programs remain internal.

For the ACT public service, the problem has a particular edge. The ACT Government's Shared Services ICT unit, which supports agencies operating out of offices across Civic, Belconnen, and Gungahlin, manages storage environments that have expanded rapidly as more services moved online. Storage is not free. Commercial cloud providers charge per gigabyte, and duplicated images represent direct, unnecessary expenditure. Industry benchmarks from the data management sector suggest duplication rates of 20 to 40 percent are common in environments without active deduplication policies — meaning a meaningful share of storage costs across any large organisation may be redundant.

The Decisions That Will Define What Comes Next

Three choices will shape how this plays out over the next twelve months. First, whether agencies opt for automated deduplication tools integrated into existing storage platforms, or commission manual audits — the former is faster but requires upfront software licensing costs that some smaller ACT bodies have been reluctant to absorb. Second, how the National Archives of Australia, based at Queen Victoria Terrace in Parkes, updates its digital preservation guidance to distinguish between archivally significant images that must be retained in multiple formats and genuinely redundant duplicates that can be purged without records obligations being breached. Third, whether the ACT Government's digital strategy, currently under development by the ACT Digital and Data Office, includes binding deduplication standards or leaves the matter to individual directorates.

Public servants in Gungahlin and Belconnen service centres — where government-facing digitisation of community documents like planning applications and licensing records has grown sharply since 2023 — are among the front-line users whose daily workflows feed the problem. Any new policy will need to account for how documents enter systems at that community level, not just how head-office servers are managed.

Procurement watchers will be paying attention to whether the Digital Transformation Agency, which advises on federal ICT spending, issues updated guidance on deduplication as part of its cloud services panel review expected later in 2026. That guidance, if it comes, could set a de-facto standard that cascades through both federal and territory agencies in the capital. The window for agencies to get ahead of the problem — rather than be forced into expensive reactive cleanups — is narrowing alongside those contract expiry dates.
